A former head of the Kansas Bureau of Investigation will give the Wichita Crime Commission a behind-the-scenes look at the agency.

Retired KBI Director Larry Welch is the featured speaker at the crime commission’s annual awards banquet Thursday evening in Wichita.

Welch’s book “Beyond Cold Blood: The KBI from Ma Barker to BTK” was released last month. It lays out some details about key cases the agency investigated from its inception through 2007.

The St. John native began his law enforcement career in 1961 with the Federal Bureau of Investigation. He was appointed director of the KBI in 1994 and oversaw the agency until his 2007 retirement.
